Abstract

The invention is a method for eliminating obliqueness of weft-knitted fabric straight texture: the invention uses yarn of two twisting directions and a twisting degree, one is S twisting, another is Z twisting alternately. Thus the adjacent two reverse torsion inner stresses are cancelled, when the underwear is washed by water, the second channel seams are at two edges, the straight texture can maintain straight.

Description

A kind of single side weft-knitting knitted fabric of eliminating is directly to the crooked method of lines

The present invention relates to a kind of weaving technology, it is directly crooked to lines particularly can to eliminate knitted fabric.

The single side weft-knitting knitted fabric is the sub-thread yarn count that adopts atural staple fibre (cotton, fiber crops) to be spun into mostly, and in spinning process, fiber forms yarn by twist obvolvent.Because twisting makes Yarn texturing, just produces an internal stress opposite with twist direction.When yarn after being bent to form coil on the single face circle latitude knitting machine needle, the release of this internal stress makes winding deformation, numerous distorted loop mutual superposition causes the crooked of fabric wale (directly to lines), and grey tube cloth is twisted.Generally speaking, Z twists with the fingers cotton yarn and present " right skew " deformation when skew takes place, and points to the oblique right-hand wale deformation; All S twist with the fingers cotton yarn and show as " left side distortion " deformation, and it makes the coil inclined-plane to left.In dyeing and finishing process, though can correct straight little crooked to lines by force by external force, this is the short time, temporary transient.When fabric is constantly shaken in cutting, sewing process, still to shift to original crooked direction, what make underwear copies the seam shift in position, and especially after the dress washing, it is even more serious to crook distortion.

Directly crooked to lines in order to overcome, the present invention takes a kind of method, and it is directly crooked to lines to eliminate its single jersey, and its wale (directly to lines) is kept upright.

The technical solution adopted for the present invention to solve the technical problems is: according to the reason of the crooked generation of unidirectional lines, can take two kinds of sth. made by twisting is that S twists with the fingers to yarn (S twist with the fingers, Z twist with the fingers) a tunnel, and one the tunnel is that Z twists with the fingers alternately and feeds to advance to weave.Two adjacent like this internal stress of crooking are round about cancelled out each other, and fabric wale (directly to lines) is kept upright, and reach to eliminate directly to the crooked purpose of lines.

Beneficial effect of the present invention: adopt the yarn count of two kinds of sth. made by twisting to (S sth. made by twisting, Z twist with the fingers) the same twist, one every an arrangement knitting, two adjacent internal stress of crooking are round about just cancelled out each other, after the underwear washing of making, two roads are copied seam and are remained at two limits, the phenomenon of turning down is not appearring rolling up

The present invention is further described below in conjunction with drawings and Examples:

Fig. 1 Z twists with the fingers to making fabric coil lower left (upper right side Skew;

Fig. 2 S twists with the fingers to making fabric coil lower right (upper left side

Skew;

Fig. 3 Z sth. made by twisting and S twist with the fingers alternately to feed and advance to make the fabric coil to be kept upright.

The specific embodiment:

In Fig. 1, adopt the Z twist yarn, large circle machine is when clockwise rotating, and Z twists with the fingers cotton yarn and present " right skew " deformation when the generation skew, refers to the oblique right-hand wale deformation; After the washing, distortion is serious.

In Fig. 2, adopt the S twist yarn, large circle machine is when rotating counterclockwise, and S twists with the fingers cotton yarn and shows as " left skew " deformation (direction is just opposite with the Z twist yarn) at the generation skew, and it makes the oblique left of coil; After the washing, distortion is serious.

In Fig. 3, adopt Z twist yarn and S twist yarn alternately to feed to advance to weave, and two adjacent internal stress of crooking are round about just cancelled out each other, after the underwear washing of making, two roads are copied seam and are remained at two limits, the phenomenon of turning down do not occurring rolling up, and knitted fabric just is kept upright.

Claims

1. eliminate the single side weft-knitting knitted fabric directly to the crooked method of lines for one kind, it is characterized in that: two twist with the fingers to alternately feeding to advance to weave.

2. a kind of single side weft-knitting knitted fabric of eliminating according to claim 1 is characterized in that directly to the crooked method of lines: two twist with the fingers to being to twist with the fingers to being that Z twists with the fingers by one, and another sth. made by twisting is that S twists with the fingers and forms.

3. a kind of single side weft-knitting knitted fabric of eliminating according to claim 1 is characterized in that directly to the crooked way of lines: in weaving process, a row is the Z twist yarn, and another row is that machine is alternately weaved on the S twist yarn.
